Composite string insulator units for overhead lines with a nominal voltage greater than 1000 V - Part 1: Standard strength classes and end fittings
Prescribes specified values for the mechanical characteristics of
the composite string insulator units. Defines the main dimensions
of the couplings to be used on the composite string insulator units
in order to permit the assembly of insulators of fittings supplied
by different manufacturers and to allow, whenever practical,
interchangeability with existing installations.
It also defines a standard designation system for composite string
insulator units.
The contents of the corrigendum of November 2007 have been included
in this copy.
